Cube Drop Puzzle

Cube Drop Puzzle sets coloured bears on a board along with coloured holes. A hole only takes the bear whose colour it matches, and the level ends when every one of them has splashed into the lake below.

Matching the colours is the easy half. The hard half is space: bears and holes sit in each other's way, and moving the wrong hole first can leave a bear stranded with nothing able to reach it.

Later levels tighten this deliberately. Fewer free squares, more bears, and arrangements where two of them both need the same gap — which means the order stops being obvious and starts being the entire puzzle.

The tone stays gentle throughout: no timer, no failure state beyond restarting a board, and a satisfying splash every time a bear finds its way down.
